Patent attributes
A vehicular interior rearview mirror assembly includes a mirror head and a mounting assembly. The mirror casing includes a sidewall having an outer end region that circumscribes an open portion of the mirror casing. The outer end region includes a rounded outer surface curving between the open portion and a less-curved outer surface of the sidewall. The mirror reflective element is disposed at the open portion of the mirror casing. The mirror reflective element has a glass substrate having a rounded perimeter edge of at least 2.5 mm and a thickness of less than 2 mm. Curvature of the rounded outer surface of the outer end region of the sidewall matches curvature of the rounded perimeter edge of the glass substrate to provide a curved transition between a flat region at the front surface of the glass substrate and the less-curved outer surface of the sidewall of the mirror casing.
